Tectono-metamorphic evolution of subduction channel serpentinites from South-Central Chile
(Elsevier, 2019)
This work provides the first comprehensive petrological and multi-scale structural investigation of a suite of ultramafic bodies and enclosing metasediments from the Late Paleozoic accretionary prism of South-Central Chile. ...
Titanian clinohumite and chondrodite in antigorite serpentinites from Central Chile: evidence for deep and cold subduction
(E Schweizerbartsche Verlagsbuchhandlung, 2017)
Humite minerals, including Ti-rich, hydroxyl-dominant chondrodite and clinohumite, occur in Paleozoic antigorite serpentinite in the La Cabana area, in the Chilean Coastal Cordillera (similar to 38 degrees 30'S- 73 degrees ...
Carbonation of mantle peridotite by CO2-rich fluids: the formation of listvenites in the Advocate ophiolite complex (Newfoundland, Canada)
(Elsevier Science, 2018-06)
The mantle section of the Advocate ophiolite (Newfoundland, Canada) contains unique outcrops of listvenite (magnesite-quartz), antigorite- and quartz-bearing talc-magnesite rock, and carbonated antigorite-serpentinite. ...
Nuevos aportes al entendimiento de la evolución geotectónica del noroccidente colombiano mediante el estudio petrográfico y geoquímico del basamento de la Cuenca Sinú-San Jacinto
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - GeologíaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022)
El basamento de la cuenca Sinú-San Jacinto recuperado en el pozo estratigráfico Las Lauras, está compuesto por serpentinitas con diferentes grados de alteración que van desde 25 a 100%, cuyo protolito más probable fueron ...
A secondary precious and base metal mineralization in chromitites linked to the development of a Paleozoic accretionary complex in Central Chile
(Elsevier, 2016)
Platinum-group element (PGE) and gold inclusions are usually present in peridotites and chromitite deposits associated with ophiolites. Here, we present the first detailed study of the mineralogy of precious metals in ...

(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en GeocienciasDepartamento de GeocienciasFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2020)
Las rocas de alta presión del Complejo Arquía, Cordillera Central de Colombia, consisten principalmente de eclogitas retrogradadas y esquistos y neises azules, así como rocas básicas, pelíticas, carbonatadas y ultramáficas ...
Double seismic zone of the Nazca plate in northern Chile: High-resolution velocity structure, petrological implications, and thermomechanical modeling
(AMER GEOPHYSICAL UNION, 2008-07-08)
This paper presents an interdisciplinary study of the northern Chile double seismic zone. First, a high-resolution velocity structure of the subducting Nazca plate has been obtained by the tomoDD doubledifference tomography ...
Petrologic characterization and tectonic implications of blueschist and greenschist facies rocks of Jambaló, Cauca
(Universidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geociencias, 2017)
Jambaló greenschist and blueschist are found in a metamorphic unit that belongs to the Arquía complex. Metamorphism of these rocks is associated with the subduction of the Proto-Caribbean under the South American plate. ...
